Typical Solutions / Equipment Features:

Typical Solutions / Equipment Features:

Large Power Transformers: Used for stepping up and stepping down voltage at different levels and for long-distance power transmission. Examples include thousand-ton transformers transported via railway for HVDC transmission projects.

Green Transformers: Such as natural ester vegetable oil transformers, which feature a high fire point and are biodegradable, enhancing both safety and environmental friendliness.

Public Transformer Power Supply Model: All distribution facilities in a community (including transformers, switchgear assemblies, etc.) are uniformly constructed, operated, and maintained by the power supply utility. This model replaces the previous dedicated transformer model managed by property management, enhancing power supply reliability and reducing construction costs for developers.

Split-Winding Transformers: Feature a "one-drags-two" capability, allowing a single transformer to supply power to two circuits simultaneously. If one circuit fails, the other can continue operating, significantly enhancing power supply reliability. This is particularly suitable for new energy projects in remote areas. 

Assembled Switchgear: Integrates control, measurement, protection, and other electrical components into prefabricated assemblies. This enhances coordination rationality, economic efficiency, and operational flexibility.
